The Diaphragm Valve is engineered to control the flow of non-corrosive or mildly to strongly corrosive media. It features a lined or unlined body, with lining materials such as natural rubber, butyl, EPDM, or hard rubber, making it suitable for various fluid types and operating temperatures. The internal design isolates the working components , such as the valve stem and bonnet, from the process media using a diaphragm, thereby enhancing corrosion resistance and extending service life. Diaphragm valves serve as a specialized type of globe valve, offering reliable shut-off and throttling functions across a wide range of industrial applications.
